The advantages of our invention as a time and labor saver will beapparent to those familiar with.shopoperations in loco- In locomotivesfitted with pedestal braces of the ordinary construction, the lining ofa set of pedestal wedges would ordinarily require from 16 to 18 hourstime of a machinist and two help-- ers', while by reason of theexemption from the necessity of-removing and replacing the 'framepedestal, a .oneof the jaws t ereof, a pedestal brace The engageeconnected to the pedestal, a removable sup pedestal braces, which isafforded by our invention, the same work can be done by a machinistand-a singlehelper in from 3 to 4: hours.

We claim as our invention and desire to secure by Letters Patent:-

1. The" combination, with a locomotive frame pedestal, of a pedestalbrace, and means, connected with said brace, for permitting theinsertion and removal of a driving box liner in and from. the pedestal,while the journal box is in position therein, without detachment of thepedestal brace therefrom. i

2; The combination with a locomotive frame pedestal, of a pedestalbrace, a removable supporting block fitting an opening therein locatedadjacent to one of the pedestal jaws and of slightly greater length thanthe Width of a driving box liner, and means for clamping the supportingblock in said opening. p v

3. The combination of a locomotive edestal Wedge fitting. on

porting block fitting in an opening in the pedestal brace of slightlygreater length than the width of the pedestal wedge, a

wedge bolt engaging the pedestal wedge at its upperend and having athreaded e11 gagement with the supporting block, and a clamping wedgebearing on't-he supporting block and on thepedestal brace.

4. The combination [of a locomotive frame pedestal, a pedestal bracehaving .ver-

tical through openings which receive the versely in the pedestalbra'ce'and bearing thereon and .fitting in the grooves of the pedestallegs, and nuts engaging threaded ends on said wedges and bearing on oneside of the pedestal brace.
